OILING SYSTEM.

To all whom it may concern: Be it known that I, ANDREW C. Denver, a citizen of'the United States, resldlng at Pawtucket, in the county of Providence and The essential objects of my invention are to insure that when the vehicle is inclined toward the vertical, as in movmg up an elevation, the forward oil pits or depresslons shall not, as now, be deprived of oil by the flow of the latter to the fly-wheel case to such an extent that the cranks will not contact with the oil surface; to insure a single extensive and deep oil area to the cranks while the vehicle is moving on'the level,

which shall be immediately converted into a plurality of individual receptacles as soon as the vehicle reaches an incline; to maintain the same oil level at the center of crank splash on the igradeas on the level; to return the super uous oil to the fly-wheel case instead of to the first of the series of pits and to attain these ends in a structure adapted for use upon an automobile without any substantial reconstruction.

To the above ends essentially my invention consists in such arts and combinations scope of the appended claims. p

In the accompanying drawings which form a part of this is a longitudinal section, partially in side elevation, of, the. crank case-and adjacent parts of an automobile, Fig. 2, an enlarged central longitudinal section of the bottom of the crank case, Fig. 3, a plan elevation of the same, Fig. 4, a section on line 14. of Fig. 2, and Fig. 5, a view similarto that of Fig. 2, showing the position of the parts when the automobile is' passing up an inchne.

' Like. reference characters indicate like parts throughoutthe views. In the drawings 6 is the crankcase, 7 the fly-wheel caseor oil reservoir, 8 the flywheel, 9 the magnets, 10 the crank shaft, 11

the cranks, 12 the crankcase oil tube, and

the adjacent parts of an automobile of the Specification of Letters Patent. 1

Ford type, and it in conjunction with i these familiar parts that my invention is particularly adapted for use. p

In detail my novel structure comprises a removable plate ,15 adapted for attachment to the bottom of the crank casing in an openmg 16 in the bottom thereof for the accommodation of the plate in front of the flywheel case. When' attached in place this plate forms a portion of the crank case. The plate is oblong in outline and is provided with transversely pits, pockets, or depressions 17 severally located immediately below and in vertical alinement with the cranks 11, and so disdisposed arcuate posed that the cranks in their rotation extend to a plane below the plane of the body of the plate. 5

Adjacent to each pit is a trough represented in a general way by the numeral 18.

Each trough comprises a-transversely dis posed vertical back wall 19 spaced some distance to the rear of the rear of its pit and spaced at its ends from the lateral edges of the plate. Integral with the ends of this wall are inclined side walls 20, parallel with the lateral edges of the plate extending to points thereon forward of the. adjacent pit thus partially inclosed thereby. These at intervals'with openings 22, to receive attaching screws or bolts 23 which pass .walls and the back wall are preferably cast through openings 24 in the crank case on which the washer rests, and through holes 25 It will be observed that between the walls 20 of the troughs and the wall 21 are formed resultant paths or channels 27 extending longitudinally of the plate 15.

When the automobile is moving on a level,

the level of the oil over thearea of 'the plate is usually the height of the wall 21,

the oil being" supplied in the usual manner" by the crank oil tube 12 from the supply of 011 28 in the fly-wheel case. This level par tially fills the pockets and partially fills the troughs. I

Whenthe automobile is passing up an elev yatlon'the parts assume the positions shown. in Flg. 5,'and a portlon of the oil flows rear- 1 wardly throughthe channels 27 into the flywheel'case, but the elevated trou hs 18 re-' tain a level of oil at their upper e gesthereby insuring a depth sufficient to immerse the. combination of a flat plate, a longitudinal series ofttransversely disposed pockets in the plate, and troughs upon the plate spaced from the pockets and surrounding the pockets on three sides only.

2. In a crankcase of the type set forth, the combination of a plate, a longitudinal series of transversely disposed pockets in the plate, and longitudinally inclined troughs upon the plate surrounding the pockets on three sides.

3. In a crank case of the type set forth, the combination of a fiat plate, a longitudinal series of transversely disposed pockets in the plate, rectangular troughs on the plate surrounding three sides only of the ockets, and walls upon the plate parallel wlth andspaced from the sides of the trough.

4. In a crank case of the type set forth, the combination of a flat plate, a longitudinally disposed series of transverse oil pockets in the plate, a vertical transversely disposed back Wall on the plate in the rear of each pocket, longitudinally disposed side walls on the plate at the ends of each back wall extending forward of the inclosed pocket and having their upper edges downwardly and forwardly inclined from the top of the back wall to the surface of the plate.

5. In a crank case of the type set forth,

the combination of a flat plate, a longitudinally disposed series of oil pockets in the plate, a transverse wall on the plate in.

the rear of each pocket, inclined vertical side walls on the plate extending from the top of the back wall to pointsforward of the pockets, and a marginal wall on the plate parallel with the side walls and spaced therefrom forming oil channels.

In testimony whereof I have affixed my signature.
